' SPRING MOUNTING FOR HAIR CLIPPERS.

Application filed March 14, 1925. Serial No. 15,464.

My invention relates to an improvement in spring mountings for hair clippers and the like, the object of the invention being to provide a simple and effective mounting for a spring whereby the tension of the spring may be readily adjusted and the parts automatically locked in adjusted position.

Gther objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed. V

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Fi 1 is a side view of a hair clipper provided witha spring mounting embodying the invention;

Fig. 2 is a top plan view of the same;

3 is a section taken on line 33 of F 1; and r 4 is an enlarged bottom plan view of an adjusting screw employed in the construction.

The preferred form of construction as illustrated in the drawings comprises a handle ineinber 5 having an enlarged housing 6 formed integrally with the lower end thereof, said housing being open at the bottom.

The bottom of the housing 6 is closed by means of a cutter head 7 removably secured thereto by means of screws 8 and provided.

with cutting teeth 9. (lo-operating with the cutter head 7 is areciprocating cutter blade 10 having teeth 11. The cutter blade 10 is engaged by a yoke or strip 12 resting loosely thereon and provided with downwardly turned lips orflanges 13 at its ends fitting snugly over the ends of the blade, said yoke providing an engagement with said blade by means of which the same is reciprocated. The reciprocation of the blade may be accomplished by any usual or desired means,

said reciprocating means constituting no part of the-present invention and therefore requiring no further description here. So much of the construction already described may be of any usual or desired form and constitutes no part of my present invention except in so far as the same co-operates with the spring mounting to be presently described.

An upwardly arched leaf spring 14 is arranged in the housing 6 to rest upon the top of the yoke 12 and thus yieldlngly press the blade 10 into operative relation With the with its ends projecting through notches 20 in the sides of housing 6 so that said spring cannot turn with reference to the housing. When the adjusting screw 17 is turned to adjust the tension of the spring 14 the end 18 of the post- 15 will snap'from one of the slots 19 to another, thus yieldingly engaging said notches to form an automatic lock for the screw 17 and whereby said screw will be automatically locked in adjusted positions; The post 15 engaging the socket 16 also tends to hold the spring rigidly in position and thus insures the exertion of "uniform pressure on the blade 7 V While I have illustrated and described the preferred form of constructionfor carrying my invention into effect, this is capable oil variation and modification without departing from the spirit of the invention. 1, therefore, do not wish tobe limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire tosecure by Letters Patent is: c g '1. The combination with a blade of a hair clipper, of a leaf spring co-operating therewith; a post fixed on said spring; and an ad justing screw provided with a socket fitting over said post, said'post engaging the bottom of said socket, substantially as described.

2. The combination with a blade of a hair clipper, of a leaf spring co-operating therewith; a cylindrical post fixed on said'spring having a flattened end; and an adjusting screw provided with a socket fitting over said post, said post engaging the bottom of said socket and said socket bottom being provided with a slot engaging the flattened end of said post, substantially as described.

3. A hair clipper comprising a handle; a housing formed integral y with said handle nd open at the bottom a cutter head at" ranged across the open bottom of said housing; a reciprocating blade on said cutter head; a leaf spring in said housing co-operating with said blade to exert pressure thereon; an upstanding cylindrical post fixed cen trally on said spring, the upper end of said post being flattened; and an adjusting screw threaded in the top of said housing and provided with a socket fitting over said post, the bottom of said socket being provided with transverse slots engagingthe flattened end of the post, substantially as described.

4. A spring mounting comprising an adjusting screwhaving a socket therein; and a leaf spring carrying post fixed thereon and fitting into said socket and engaging the bottom thereof, substantially as described.

5. A spring mounting comprising an ad'- justing screw having a socket therein, the bottom of said 'socketbeing provided with one or more transverse slots; and a cylindrical post fixed centrally on said spring and having, a flattened end, said post fitting into saidsooket and said'fiattenedend engaging said slots, substantially as described. 6,..The combination with a blade of a hair clipper, ofaleaf spring resting thereon, said spring being upwardly arched at the center and bearing upon said blade at its ends; a

post fixed onthe central arched portion of said spring; and an adwstable screw provided with a socket fitting over said post,

said post engaging the bottom of said socket, substantially as described.

7. The combination with the stationary blade ofa hair clipper, of a reciprocating blade operating on top of said stationary blade; a leaf spring restingon top of said reciprocating blade, said leaf spring being upwardly archedat the center and caring upon said blade at its ends; a post fixed on the upwardly arched central. portion or" said spring; a housing arranged over said blade, and spring; andan adjustable screw thread ed in said housing and provided with a socket fitting over said post, said post engaging the bottom of said socket, substantially as described.

8. The combination with the stationary blade of a hair clipper, of a reciprocating, blade operating on top of said stationary blade; a leaf spring resting on top of said.

sprin reciprocating blade, said leaf spring being upwardly arched at the center and bearing upon said blade at its ends; a post fixed on the upwardly arched central portion ofsaid a housing arranged over said blade and spring; and anadjustable screw threaded in said housing and provided with a socket fittingoversaid post, said post engaging the bottom'of said socket, the bottom of said socket being provided with'transverse slots and the top of said post being flattened, to engage said slots, substantially as described.

9. The combination with the stationary blade of a hair clipper, of a reciprocating blade operating on top ofsaid stationary blade; a leaf spring resting on top of said reciprocating blade, said leaf spring being upwardly arched at the center and bearin upon said blade at its ends; a post fixe on the upwardly archedcentral portionof said spring; a housing arranged over said blade'and spring, the ends of said housing being notched and'the ends of said spring fitting into said notches; and-an adjustable screwthreaded in said housing andprovided with a socket fitting over said post said post engaging the bottom of said socket, sub stantially as described.

10. The combination with the stationary blade of a hair clipper, of a reciprocating blade operating on top of said stationary blade; a leaf spring resting on top of said reciprocating blade, said leaf spring being upwardly arched at the center and bearing upon said blade at its ends; a post fixed on the upwardly arched central portion of said spring; a housing arranged over said blade and spring, said housing beingnotched at its ends and the ends oi. said spring fitting into said notches; and an adjustable screw threaded in said housing and provided with a socket fitting over said post, said post engagingthe' bottom of said socket, the bottom of said socket being provided with transverse slots and the top of said post being flattened to engage said slots, substantially as described.

In testimony whereof I have signed my name to this specification,
